AMD Radeon R5 M330 is not listed in Blender Preferences
After a quick search I found this:

OpenCL is supported for GPU rendering with AMD graphics cards. Blender supports graphics cards with GCN generation 2 and above. 
https://docs.blender.org/manual/en/dev/render/cycles/gpu_rendering.html 

Your GPU is GCN 1st generation.
